SKIVING-MA CHINE Specification of Letters Patent.

Application filed October 13,

'1906. Serial No. 338,844.

To all whom it may coacem: j

Be it known that I, PER-LEY R. GLASS, a I

ton, county of Suitolk, and State'of Massaj chusetts, have -invented-an Improvement in, Skiving-Machines, of which the following I description, in. connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

In the use of skiving machines employing circular or disk cutters, it is he uently necj essary' to adjust the cutter so t at its edge move si-rr-a path more or less distant from a vertical line intersecting the longitudinal aXis of a feed wheel, such adjustment being required in order toafiord the proper spacebetween the cutter and the top of the feed wheel, and to adapt the machine to the class of stock being skived, as the same varies in hardness and also-in thickness. The-gage a position as close as possible to the edge of the knife, and the gage must be adjusted with relation to the 'feed wheel to properly present the material to the cutter in the varying position of the gage.

The adjustment of the gage transversely with relatlon to the length of the feed wheel adjustment and the change of position of the gage with relation to a vertical line intersecting the longitudinal center of the feed wheel increases the space between the under side of the foot or edge bearing portion ofthe gage and the top of the feed wheel. Heretofore, making this over center adtime, and frequently the bottom or foot of haste be filed to adapt the same to its new position. In accordance with my invention I ave combined with a gage means whereby the same may be adjusted in a circle about the longitudinal-axis of the feed wheel sustainmg the work that the gage serves to guide,- said adjustment being also over the center and being capable of being made easily and quickly, without disturbing the longitudinal ad ustment of the gage.

' Fi ure 1 in side elevation shows a gage of cordance with my invention by means of good form of adjusting means; Fig. 2 is a left hand elevation of the parts shown in shaft feed wheel C, and the base D having a leg d,

and the yielding top plate D connected to the base by a screw PatentedJune- 1 5, 1909.-

or plan view of Fig. 1. Fig.4 shows a medi In the drawing, the framework A, the

B sustained therein and carrying the gage comprising the d, said top platehaving a foot-or bearing portion d are and may be all as common and as shown m an apphcation Serial Non 324,134 filed June 30, 1906.

The base D is slotted at d and the slot embraces a fin or projection (1 to uide the base of the gage when the latter is being adjusted longitudinallyof the shaft" B on the.

block G to which said base "-is connected "by a thumb screw 6 having a threaded base that enters a threaded hole in the block Gr, said block bein framework by a screw G The block G, see Fig. 2, is concaved at its gage sustaining connected to the? inner edge to fit the frame part A and is grooved to constitute a raceway g for the reception of an arm or extension g re resented as segmental in shape, said arm eing extended from the base of the gage. This extension, as shown in the plan in which I have herein chosen to illustrate my invention in one of its best forms, is toothed as at g that it may be engaged by the teeth of a worm toothed adjusting device 9 shown as a screw having a milled head 9 and mounted to be rotated in a cap 7L connected tothe. block G by screws h. The upper end of the screw has a shoulder that abuts a lip on the cap h and the portion of the upper end of the screw that is extended through the cap is unthreaded, presenting a shoulder substantially at the outer edge of the cap beyond which the end of the screw is threaded.

The threaded upper end of the screw receives a washer it provided with a finger,

the washer resting on a shoulder of the screw and being clamped thereon by a nut it ,said washer and finger constituting an index. The cap it has a stop h and the upper side of the cap has a scale, as shown in dex may be rotated when the "screw 9 is rotated and when the index occupies the position, Fig. 3, with the finger against the stop, the back or left hand edge d? of thegage stands practicall in a vertical line ill-- 1g. 3. The interscoting the longitu inal axis of], the feed wheel, and. when the screw is turned to adjust the gage over center, the finger of the index traverses over the scale and shows to the operator just the extent of adjustment over center of the gage. The yielding to late of the gage has a hole through which is extended a screw post (i carried by the base D, said post bein surrounded by a spring (1 and having app ied to its upper end a nut d which may be adjusted to regulate the ressure of the foot or bearin (1 on the stoch passing between it and the 'eed wheel.

From the foregoing description, it will be understood that the gage sustaining block G may be adjusted transversely the "longitudinal axis of the feed wheel, and that the base of the gage may be adjusted longitudinally on said block.

In the modification Figs. 4 and 5, I have shown the gage body D as provided with an extension M' represented as a curved arm concaved at its inner side to fit the portion g of the block Gr, said extension having a slot m. I have extended from the ortion g a clamp-screw at one end of w ich is threaded into said portion, the shank of the clamp screw being extended through the slot M, and by loosening the clamp stud the gage may be turned in a circular path about the Ion itudinal axis of the feed wheel carrying sha as hereinbefore provided for.

Having fully described my invention, what gage about the longitudinal axis of said feed wheel.

2. In a machine of the class described, a

feed wheel, a gage, and means to adjust said gage over center with relation to the longitudinal axis of said feed wheel.

3. In a machine of the class described, a feed wheel, a block having a raceway, a gage having an extension entering said raceway, and adjusting means co-acting with said extension to'-."ad ust said gage transversely with relation to the longitudinal axis of said feed wheel.

4. In a machine of the class described, a feed wheel, a block having a raceway, a gage having a toothed extension entering said raceway, and means engaging the teeth of said extension to adjust the gage trans- I versely to the longitudinal axis of the feed wheel.

In testimony'whereof, I have signed my name to this specification, inthe PIQSOIH'U of two subscribing witnesses.
